The Discoverer A/T3XLT is Cooper's On-Road All-Terrain tire designed for the drivers of pickup trucks, work vehicles and full-size SUVs who need a tire that provides the rugged durability required to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer A/T3XLT combines off-road prowess with agreeable on-road comfort and year-round traction, including in light snow.
Durable-Tread Technology combines a shred-resistant silica compound with the Discoverer A/T3XLT's next-generation all-terrain tread pattern. Cooper's Even Wear Arc Technology optimizes the shape of the footprint for balanced pressure at the contact patch, improving handling and promoting even treadwear. The tread pattern is designed to aid dry traction, while Whisper Grooves between the outboard tread blocks help reduce noise throughout the tire's life. Stone ejector ledges help prevent punctures due to stone drilling, and the Rugged Traction Shoulders feature alternating scoop and cleat lugs and biting edges designed for grip on rock, in thick mud or loose soil. Deep, circumferential channels and wide, lateral notches improve hydroplaning resistance, while multiple zigzag sipes in the independent tread blocks create the biting edges needed for traction in slippery conditions. Snow Groove Technology uses saw-tooth block edges to trap snow in the tread for effective snow-to-snow traction.
The internal construction of the Discoverer A/T3XLT consists of a robust, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.
El neumático Discoverer A/T3XLT de Cooper pertenece a la categoría: Dentro/Fuera De Carretera Todoterreno y ha sido diseñado para conductores de picops, vehículos para trabajo y utilitarios deportivos (SUV, por sus siglas en inglés), que necesitan un neumático que proporcione la fortaleza y durabilidad requerida, para mantener las actividades de sus estilos de vida. Construido para lidiar con lodo, grava, tierra polvorienta y la jungla urbana, el Discoverer A/T3XLT, combina habilidad todoterreno con un confort agradable en la carretera y tracción durante todo el año, inclusive en superficies con poca nieve.
La tecnología "Durable-Tread" combina un compuesto de caucho con sílice resistente a roturas, con el patrón todoterreno de la generación siguiente del Discoverer A/T3XLT. La tecnología de Cooper "Even Wear Arc", optimiza la forma de la huella, para obtener una presión balanceada del área de contacto, y así, mejorar la maniobrabilidad y obtener un desgaste parejo. El diseño del patrón en la banda de rodamiento mejora la tracción sobre superficies secas, mientras que, ranuras "Whisper Grooves" entre los bloques externos ayudan a reducir el ruido durante el ciclo de vida del neumático. Rebordes expulsores de piedras previenen pinchazos causados por piedras incrustadas. Hombros fuertes para obtener tracción, "Rugged Traction Shoulders", contienen bloques con espacios y dientes alternados, además cuenta con bordes adherentes diseñados para obtener tracción sobre piedras, lodo y superficies sueltas. Canales profundos circunferenciales y ranuras laterales anchas, mejoran la resistencia al deslizamiento sobre agua (hydroplaning), mientras que, pequeñas ranuras tipo zigzag en los bloques independientes, crean los bordes adherentes necesarios para obtener tracción sobre superficies en condiciones resbalosas. La tecnología "Snow Groove" utiliza bordes serrados en los bloques, para atrapar nieve y hacer más efectiva la tracción nieve con nieve.
La construcción interna del Discoverer A/T3XLT consiste de una estructura robusta de dos capas de poliéster. Una capa de refuerzo de nailon, por encima de dos correas de acero de gran fortaleza aumenta, aún más, la durabilidad y la respuesta al girar el volante, además de proporcionar estabilidad a velocidades elevadas.

...For reference my tire size has 11/32 tread new. Both front tires were at 9.2/32 and Both rear tires were at 10.75/32. Going forward I will be rotating them every 6-7k but was happy to see such little wear on the rears...
I just did my first tire rotation at 9,990 miles today and measure my tread depths with a caliper. For reference my tire size has 11/32 tread new. Both front tires were at 9.2/32 and Both rear tires were at 10.75/32. Going forward I will be rotating them every 6-7k but was happy to see such little wear on the rears. I doubt they will last the 75k they have a tread warranty for but that'd be great if they do.
I only notice road noise from these when going 60mph+ and having to slightly turn the wheel through curves. It'll go from silent to a little noise until you straighten back out.
The tires have been great for my little car and have exceeded my expectations in the snow. After looking at the snow ratings and tread design I was ready to get a set of snow tires but gave it a few snow falls to test drive and I've felt so stable I didn't buy new tires or switch these.
